Title: Ring type lan address designation system
Inventor: TONE KAZUYUKI
Filed: 1987-04-16
Abstract: PURPOSE:To eliminate an error frame from a transmission line by discriminating its own node address from a value being the addition of 1 to a value of a counter field in a frame and a value of an opposite destination address field in each node. CONSTITUTION:The number of nodes is set to the opposite destination address field 6 in a frame passing till a destination node in each node and a counter field 7 is set initially. Each node uses an adder circuit 2 at the frame reception to add to a value set to the field 7 by '1' and the result is compared with the value of a field 6 at a comparator circuit 3. When the both are concident, the result is fetched as its own node frame and when the frame is smaller, the result is sent to the next node. In such a case, when the value being added with '1' to a value set to the field 7 is larger, the frame is excluded as a faulty frame.

Title: Image transfer multiple laser beam amplifying device
Inventor: KURODA JUNJI
IPC: H01S3/101
Filed: 1985-05-02
Abstract: PURPOSE:To improve beam opening utilization efficiency by providing a spatial filter consisting of a pair of lenses and a pin hole and an optical system for transferring and projecting the image of a laser beam on its input lens again onto the input lens. CONSTITUTION:A device is constituted of reflecting mirrors 1, 2, a laser medium 3, lenses 4, 5, a pin hole 6, switching elements 7, 8 for converting a polarizing direction and a polarizer 9. As for an incident laser beam, its deflecting direction is varied by operating a switching element 8 and it reciprocates between the reflecting mirrors 1, 2. While executing one reciprocating motion, the laser beam is amplified by passing through the laser medium 3 two times, and emitted in the direction opposite to an incident side from the polarizer 9, by operating the switching element 7, after several reciprocating motions. In this stage, in case of d1=d2=f, the image of the lens 5 is transferred to the lens 4 and subsequently, the image of the lens 4 is also transferred to the lens 5. In this way, diffracting effect of the laser optical beam is reduced and the beam opening utilization efficiency is improved.

Title: Apparatus for preventing transient vibration of convergent beam of scanner
Inventor: GHOSH SYAMAL K
IPC: B41J2/44
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To prevent an undesirable virtual image from being formed at a write element because of transient vibrations, by coating an image formation container with a laser-absorbing coating which absorbs a convergent laser light and substantially eliminates transient vibrations when a write laser light converges. SOLUTION: A black chromium coating 330 is provided to a housing 305 forming an image formation drum 110 with the use of electric plating, heat spraying, physical vapor deposition or the like manner. The black chromium coating 330 has a feature of absorbing electromagnetic waves of 900-1000 nm which is a wavelength of convergent beams. When the convergent beams are projected to the image formation drum 110, because of a gap between a leading edge and a rear edge of a receiving element, the coating 330 absorbs totally or substantially totally convergent beams which would be reflected from a surface of the drum without the coating, thereby preventing transient vibrations from being brought about by the reflected beams to converging write laser beams.

Cooling air 27 is absorbed from outside of the blower and is discharged again outside of it through a duct 25. Heating air and cooling air flow side by side putting a thin plate of the blade 11 between, and circulating air is cooled and dehumidified, contained moisture being condensed and discharged. In the inner periphery of the participle plate 22, a rocking body 29 having flexibility is provided, and the sliding part 30, which slides with the seal material 15 are provided in that inner periphery. Since the sliding part is always positioned nearly at the center of the V type of the section of the seal material, the rotation torque is reduced, and the durability is improved.
